Screw retention sleeve
A surgical screw driving device for driving a screw into a surgical fixture. The device has a screwdriver having a proximal end, a distal end having a driver for engaging the screw, and an elongated shaft extending therebetween. The device has a screw retainer surrounding and extending along the elongated shaft. The screw retainer is configured to engage and hold a periphery of a screw head prior to the screw being driven into the surgical fixture. The screw retainer is configured to disengage from the periphery of the screw head as an axial end of the screw retainer contacts the surgical fixture and is further configured, upon disengagement and without necessity of outside assistance, to translate along the elongated shaft of the screwdriver away from the distal end and toward the proximal end.
Slogging wrench
A slogging wrench (10) comprising: a ring socket (36) for receiving a nut or a bolt head (NBH, NBH); an elongate body (20) for receiving blows from a mass to transmit torque to the ring socket; and a tool-free locking mechanism (22,24,26,26,28,30) for retaining a nut or a bolt head in the ring socket. The locking mechanism comprises a slider (22) operable to engage a nut or a bolt head in the ring socket; a channel (24) for guiding movement of the slider towards and away from the ring socket; and an actuator (30,74) manually operable to move the slider with respect to the ring socket. The channel (24) opens into the ring socket (36) via an internal periphery (40) of the ring socket. The locking mechanism comprises a resilient member (34) biasing the slider (22) towards a nut or a bolt head (NBH, NBH) in the ring socket (36).
Quick disconnect tool, quick disconnect male connector and methods of using the quick disconnect and male connector to connect a device to a vehicle wheel
Provided are a quick disconnect tool and a male connector. The tool includes a socket, detents in the socket and a collar to open and close the detents. The male connector fits within the socket and cannot rotate within the socket. The male connector includes a recess into which the detents can lock the male connector inside the socket.
HEADLESS COMPRESSION SCREW DRIVER SYSTEM
A compression screw driver system including a drive member having a shaft extending from a proximal end to a distal end. A drive selection member is positioned about the shaft and is axially moveable along the shaft between an engagement position and a disengaged position. A distal portion of the drive selection member defines a first engagement structure. A compression sleeve is positioned over the distal end of the shaft. The proximal end of the compression sleeve defines a second engagement structure which complements the first engagement structure and the distal end of the compression sleeve defines a contact surface. In the engagement position the first and second engagement structures are engaged and the compression sleeve rotates with the drive member and in the disengaged position the first and second engagement structures are disengaged and the compression sleeve remains stationary while the drive member rotates.

A drive selection member is positioned about the shaft and is axially moveable along the shaft between an engagement position and a disengaged position. A distal portion of the drive selection member defines a first engagement structure. A compression sleeve is positioned over the distal end of the shaft. The proximal end of the compression sleeve defines a second engagement structure which complements the first engagement structure and the distal end of the compression sleeve defines a contact surface. In the engagement position the first and second engagement structures are engaged and the compression sleeve rotates with the drive member and in the disengaged position the first and second engagement structures are disengaged and the compression sleeve remains stationary while the drive member rotates.
Fastener staging and placement system and method of using the same
A fastener staging and placement system comprising a staging member capable of temporarily attaching to structures and storing a plurality of ring type fasteners, and a placement member with a means for gripping and removing one or more fasteners to and from the staging member. The staging member comprises a removable and substantially vertically oriented dowel, configured to present a series of ordered sets of fasteners to the placement member, and an attachment means that may be removably attached to various structures. The placement member comprises two or more gripping arms that are configured to flex and exert pressure on at least one fastener thereby securing an ordered set of fasteners.
Combination including a ratchet wrench and a driving member
A combination includes a ratchet wrench and a driving member. The ratchet wrench includes a body and a ratchet wheel mounted in the body and rotatable relative to the body about a rotational axis. A driving hole extends through from a side through the other side of the body along the rotational axis and includes an inner periphery having a plurality of abutment surfaces. A corner is formed between each two adjacent abutment surfaces. At least one limiting portion protrudes from the inner periphery of the driving hole in a radial direction perpendicular to the rotational axis. The driving member includes at least one evasive portion and is coupled to the driving hole. The driving member is movable between a first coupling position and a second coupling position along the rotational axis when the at least one evasive portion is aligned with the at least one limiting portion.
SCREWDRIVER WITH FORCE APPLYING MEMBER
A device for driving a fastener has a shaft and a driving portion formed on an end of the shaft. The driving portion is provided with one of a slot and a channel for securely holding a force applying member formed from a resilient material. When a tip of the driving member is positioned within a tip receiving portion tip portion of the fastener, a surface of the force applying member which faces towards the head of the fastener will frictionally engage with the head portion of the fastener to prevent the driving portion from slipping from the fastener.
PUSH-OFF DRIVER AND METHOD FOR INSERTING BONE SCREWS
A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to push-off the polyaxial screw from the inner driver.
SCREW CLAMPING DEVICE
A screw clamping device includes a body, a pressing unit, a resilient unit, a clamping unit and a connecting unit. The body is a hollow-core cylinder, is subject to axial penetration of a screwdriver, and is movable axially in synchrony with rotation of the screwdriver. The pressing unit is disposed on the body and adapted to press against a surface of a working object. The resilient unit is disposed between the body and the pressing unit. The clamping unit is rotatably connected to the body. The connecting unit has one end connected to the pressing unit and the other end connected to the clamping unit. While the body is moving axially, the connecting unit drives the clamping unit to rotate and thereby clamp or loosen screws.
